Description

[Technical field]

[0001] The present invention relates to a gaming machine. [Background technology]

[0002] As a gaming machine, a slot machine is known that is equipped with a plurality of reels with a plurality of symbols arranged on the outer periphery, a start lever, a stop button, etc. In the slot machine, the reels start to rotate based on a game start operation, and an internal lottery is performed using a lottery table. When each reel stops, a symbol combination corresponding to a winning combination that has been selected in the internal lottery is displayed, and when the winning combination is a winning combination, a process corresponding to the winning combination is performed, such as a medal payout process that pays out medals (game value) or a replay process that allows a player to play again without consuming medals.

[0003] Some of such gaming machines are provided with heat dissipation holes in the back panel (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2006-43312 A Summary of the Invention [Problem to be solved by the invention]

[0005] Meanwhile, in the field of gaming machines, there is a demand for gaming machines that combine noise suppression effects with component damage suppression effects.

[0006] The present invention has been made in consideration of the above circumstances, and has an object to provide an amusement machine which combines noise suppression effects and component damage suppression effects. [Means for solving the problem]

[0007] In order to achieve the above object, the gaming machine according to the present invention comprises: A gaming machine equipped with a cabinet (e.g., cabinet 1), A back plate (e.g., back plate 3) that constitutes the outer shape of the housing is provided with a metal sheet (e.g., sheet 40) on the inner side, the back plate includes a first back plate opening (e.g., a wiring opening 72) for passing wiring (e.g., an outer end plate harness); The sheet has a first sheet opening (e.g., sheet opening 42) for passing the wiring therethrough; The first back panel opening is such that a first back panel inner surface opening (e.g., first back panel inner surface opening G) on the inner surface side of the back panel is larger than a first back panel outer surface opening (e.g., first back panel outer surface opening F) on the outer surface side of the back panel, The first sheet opening is adapted to mate with the first back panel inner surface opening.

[0008] If the wiring comes into contact with the metal sheet, the sheet may curl or peel off, and the peeling of the sheet may cause failure of components inside the housing. Also, the wiring may be scratched and damaged (such as broken wires). In the gaming machine according to the present invention, the first sheet opening is aligned with the first back panel inner side opening. This makes it possible to prevent contact between the wiring and the metal sheet, and to prevent the occurrence of such problems. Furthermore, by providing a metal sheet on the inner side of the back panel, noise resistance performance can be improved. This makes it possible to provide a gaming machine that combines noise countermeasure effects with component damage prevention effects. Effect of the Invention

[0009] According to the present invention, it is possible to provide an amusement machine that combines noise suppression effects and component damage suppression effects. [Brief description of the drawings]

[0028] The power supply unit 10 is in the shape of a roughly rectangular parallelepiped box, is located at the lower left inside the housing 1 (placed on the bottom plate 4), and is fixed to the inner surface of the left side plate 5. The power supply unit 10 is equipped with a power switch (not shown), and when the power switch is turned ON, power is supplied from the power supply unit 10 to each component. Note that some components may be configured to receive power even when the power supply unit 10 is OFF. A power cable (power harness) that is connected to a power outlet that supplies commercial power (AC 100V) is connected to a power connector provided on the back of the power supply unit 10. Specifically, a connector provided at one end of the power harness is connected to the power connector, and a plug provided at the other end of the power harness is connected to the outlet. The power supply board of the power supply unit 10 creates a DC power supply (e.g., 5V, 12V, 24V, etc.) from the power sent from outside the gaming machine via the power harness, and supplies power to each component of the gaming machine.

[0029] 1, a door key cylinder 66 is provided on the front door 20, and the front door 20 can be unlocked by inserting a door key into the door key cylinder 66. Specifically, the front door 20 can be unlocked by rotating (twisting) the door key inserted into the door key cylinder 66 clockwise from its initial position. In addition, an error can be cleared by rotating (twisting) the door key inserted into the door key cylinder 66 counterclockwise from its initial position.

[0030] When medals are inserted into the medal insertion slot 34, the slot machine 100 sets the inserted medals to an inserted state up to a specified number (specified insertion number). The slot machine 100 is also capable of storing (accumulating) up to 50 medals as credits, and when the MAX BET button 35 is operated with medals stored as credits, the stored medals are set to an inserted state up to a specified number.

[0031] In the slot machine 100, when medals are inserted through the medal insertion slot 34 or the MAX BET button 35 is operated to bet a specified number of medals, the operation of the start lever 32 is enabled, and the machine is in a state in which it is possible to start playing. When the enabled start lever 32 is operated, the machine starts playing. When the game starts, each reel starts to rotate, and when the rotation speed of each reel reaches a certain speed and the reel starts to rotate at a steady speed, the operation of the stop button 33 is enabled. When the enabled stop button 33 is operated, the reel corresponding to the operated stop button 33 stops rotating. When all the reels stop, a process of paying out medals according to the result of the game or a process of making it possible to start playing again without consuming new medals is performed, and one round of play ends.

[0032] Inside the slot machine 100 (cabinet 1), boards such as a main control board (main control means) and a sub-control board (sub-control means) are provided. The sub-control board may be provided on the back side of the front door 20.

[0033] The main control board receives input signals from input means such as the MAX BET button 35, the start lever 32, the stop button 33, etc., performs various calculations to execute the game, and controls output means such as the reel unit 14 and the hopper unit 11 based on the calculation results. The sub-control board receives signals (information) sent from the main control board, performs various calculations to execute effects, and controls various effect devices such as the liquid crystal display and speaker based on the calculation results.

[0034] The main control board and the sub-control board are electrically connected, and various information (signals) such as information indicating the game status can be transmitted from the main control board to the sub-control board, but information cannot be transmitted from the sub-control board to the main control board. The functions of each board, such as the main control board and the sub-control board, are realized by hardware such as various processors (CPU, DSP, etc.), ICs, or information storage media such as ROM and RAM, or software consisting of a predetermined program pre-stored in ROM, etc.

[0035] The main control board is provided with a setting change key cylinder (not shown), a setting change button (not shown), etc. The setting change key cylinder and the setting change button may be provided in the power supply unit 10, for example.

[0036] FIG. 3 is a perspective view showing the inside of the cabinet 1 of the slot machine 100. An external terminal board 67 is provided inside the cabinet 1. In this embodiment, the external terminal board 67 is attached to the inner surface of the right side plate 6. The external terminal board 67 is provided to connect the gaming machine to an external electronic device (such as a data display device or hall computer), and various external information signals indicating the status of the gaming machine are output from the external terminal board 67 to the external electronic device. One end of an external end board harness (external end board cable) is connected to the connector of the external terminal board 67, and the other end of the external end board harness is connected to the external electronic device.

[0037] 4 is a view of the housing 1 as seen from the front side. A metal sheet 40 (shielding sheet) is attached to the inner surface (substantially the entire inner surface side) of the back plate 3. The metal sheet 40 is provided to prevent external noise from affecting various components (such as circuit boards) arranged inside the housing 1 (causing the components to malfunction, etc.). In other words, the sheet 40 is provided to improve noise resistance. The thickness of the sheet 40 is less than 1 mm, and in this embodiment, it is about 0.1 mm to 0.3 mm.

[0038] The back plate 3 has a plurality of openings (back plate openings). The plurality of openings include a wiring opening 70 (first back plate opening) for passing (passing) wiring (harness), a heat dissipation opening 80 (second back plate opening) for dissipating heat inside the housing 1 to the outside, and a supply opening 90 (third back plate opening) for supplying game medals from the back side (outer surface side) of the housing 1 to the inside (hopper unit 11) of the housing 1. Although not shown in the figure, a cover member that can be opened and closed is attached to the supply opening 90, and when the cover member is opened, the inside of the housing 1 can be accessed from the back side of the housing 1.

[0039] At least one wiring opening 70 is provided. In this embodiment, the wiring openings 70 include at least a wiring opening 71 for passing a power harness connected to the power supply unit 10 and a wiring opening 72 for passing an outer end plate harness connected to the external terminal board 67. The harness (power harness or outer end plate harness) is configured by covering a conductor (copper wire) with an insulator (insulating material: for example, polyvinyl chloride).

[0040] At least one heat dissipation opening 80 is provided, and in this embodiment, three heat dissipation openings 80 are provided. It can be said that the heat dissipation openings 80 are not openings for passing a harness through (for putting things in and taking them out).

[0041] In this embodiment, first, sheet 40 is attached to a back panel 3 without any openings, and then holes are made in both the back panel 3 and sheet 40 with a drill or the like, so that each opening and the corresponding sheet openings are formed.

[0042] The shape of the wiring opening 70 is substantially circular (round hole, elongated hole, etc.) Note that the shape of the wiring opening 70 is not limited to the substantially circular shape, and may be substantially quadrangular (square, rectangle, etc.). The shape of the heat dissipation opening 80 is an elongated hole (or a rectangle) that is long in the left-right direction. The shape of the heat dissipation opening 80 is not limited to an elongated hole, and may be a round hole (or may be substantially circular) or may be substantially rectangular. The refill opening 90 has a substantially rectangular shape.

[0043] (Specific processing) The wiring opening 70 has been subjected to the special processing described below. On the other hand, no special processing has been applied to the heat dissipation opening 80. In other words, the wiring opening 70 is an opening (hole) that has been subjected to the special processing, but the heat dissipation opening 80 is an opening (hole) that has not been subjected to the special processing.

[0044] The specific processing includes a countersinking process. FIG. 5 is a perspective view of the wiring opening 72 for passing the outer end plate harness from below on the front side. FIG. 6 is a cross-sectional view taken along the line AA shown in FIG. 4. The countersinking process here means a process for forming a step portion at the opening (edge). The countersinking process-applied wiring opening 72 includes a small opening 72a and a large opening 72b as shown in FIG. 6. The small opening 72a is formed on the outer surface (outside) of the back plate 3 (housing 1). The depth (front-rear width) of the small opening 72a is about 13 mm. The large opening 72b is formed on the inner surface (inside) of the back plate 3 (housing 1). The depth (front-rear width) of the large opening 72b is about 2 mm.

[0045] The diameter (inner diameter) of the small opening 72a is about 30 mm. Here, for the wiring opening 72, if the opening (edge, opening end) on the outer surface side of the back plate 3 is defined as the "first back plate outer surface opening F", the diameter of the first back plate outer surface opening F is about 30 mm.

[0046] The diameter (inner diameter) of the large opening 72b is about 40 mm. Here, for the wiring opening 72, if the opening (edge, opening end) on the inner side of the back plate 3 is defined as the "first back plate inner side opening G", the diameter of the first back plate inner side opening G is about 40 mm.

[0047] In this embodiment, the first rear panel inner surface opening G is larger (in diameter) than the first rear panel outer surface opening F.

[0048] The step X in the wiring opening 72 has a depth of about 2 mm and a width of about 5 mm. The step X is formed around the entire circumference of the hole. Of the small opening 72a and the large opening 72b, the small opening 72a is the one that is formed to penetrate in the front-to-rear direction, and therefore in this embodiment, the small opening 72a may be referred to as a "through hole."

[0049] Although a redundant explanation will be omitted, the wiring opening 71 for passing the power harness is also countersunk like the wiring opening 72, and has a small opening, a large opening, a step portion, an opening on the outer surface of the first back panel, and an opening on the inner surface of the first back panel.

[0050] 7(a) and 7(b) show a case where a process other than the countersinking process is performed on the wiring opening 72. In this embodiment, the specific process is the countersinking process, but the specific process may be the C chamfering process shown in FIG. 7(a) or the R chamfering process shown in FIG. 7(b). Even when the C chamfering process or the R chamfering process is performed in this way, the first back panel inner surface opening G is larger (in diameter) than the first back panel outer surface opening F. The specific process can be said to be a process that makes the first back panel inner surface opening larger than the first back panel outer surface opening.

[0051] In this embodiment, the wiring opening 70 (wiring opening 71 and wiring opening 72) for passing the harness is specially processed, and the opening on the inner surface side of the back panel 3 (housing 1) of the wiring opening 70 is larger than the opening on the outer surface side of the back panel 3.

[0052] The sheet 40 has a sheet opening (sheet opening) corresponding to the wiring opening 70. As shown in FIG. 6, the sheet opening corresponding to the wiring opening 72 is referred to as the sheet opening 42 (first sheet opening). The sheet opening 42 is formed so as to align (match) with the first back panel inner surface opening G (not the first back panel outer surface opening F). To align (match) means that the openings (diameters) are the same or approximately the same. Although a redundant description will be omitted, the sheet opening (first sheet opening) corresponding to the wiring opening 71 for passing the power harness is also formed so as to align (match) with the first back panel inner surface opening of the wiring opening 71. In this embodiment, the sheet opening corresponding to the wire opening 70 is formed to be larger than the through hole of the wire opening 70 (for example, the small opening 72a shown in FIG. 6).

[0053] By matching the sheet opening (first sheet opening) corresponding to the wiring opening 70 with the opening on the first back panel inner surface side (by shifting the position of the end of the sheet 40 outward), the harness can be prevented from coming into contact with the sheet 40. By preventing the harness from coming into contact with the sheet 40, the following effects are achieved. (1) When the harness comes into contact with the sheet 40, the end of the sheet 40 is turned up, a part of the sheet 40 is peeled off (partially torn), and the peeled off sheet 40 comes into contact with the board in the housing 1, causing a short circuit (component failure), and other problems can be prevented from occurring. (2) When the end (edge) of the harness comes into contact (rubs) with the sheet 40, the harness can be damaged (the harness coating is torn), causing a disconnection, and other problems can be prevented from occurring. In addition, if the harness coating is peeled off and the conductor is exposed, the possibility of the conductor coming into contact with the sheet 40 (becoming electrically conductive) can be reduced. According to this embodiment, it is possible to provide a gaming machine that combines the noise suppression effect of the sheet 40 and the component damage (breakdown) suppression effect of the specific processing.

[0054] FIG. 8 is a view of the supply opening 90 seen from diagonally above. In this embodiment, as shown in FIG. 8, the supply opening 90 is also countersunk (a step portion Y is provided). The supply opening 90 has a small opening 91 (first back panel outer surface side opening L), a large opening 92 (first back panel inner surface side opening M) and a step portion Y. The step portion Y has a depth (depth) of about 8 mm and a width (circumference) of about 20 mm. The sheet 40 has a sheet opening 43 (third sheet opening) corresponding to the supply opening 90. The sheet opening 43 is formed so as to align with the first back panel inner surface side opening M (rather than the first back panel outer surface side opening L). By aligning the sheet opening 43 with the first back panel inner surface side opening M (by relieving the position of the edge of the sheet 40 to the outside), it is possible to prevent the game medals and the like from coming into contact with the sheet 40 when supplying the game medals to the hopper unit 11, and the sheet 40 from turning over (peeling off).

[0055] FIG. 9 is a cross-sectional view taken along line BB in FIG. 4. In this embodiment, no specific processing is performed on the heat dissipation opening 80 through which the harness does not pass. Therefore, the heat dissipation opening 80 is formed so that the first back plate inner surface opening P is aligned (matches) with the first back plate outer surface opening Q over the entire circumference. In other words, the size (diameter) of the first back plate inner surface opening P and the first back plate outer surface opening Q are the same. It can also be said that the heat dissipation opening 80 does not have a step portion and is composed only of a through hole. Unlike the wiring opening 70, the opening on the inner surface side of the back plate 3 (housing 1) of the heat dissipation opening 80 does not extend outward beyond the opening on the outer surface side of the back plate 3.

[0056] The sheet 40 has a sheet opening 44 (second sheet opening) corresponding to the heat dissipation opening 80. The sheet opening 44 is formed to be aligned (match) with the first back panel inner surface side opening P. In the heat dissipation opening 80 through which the harness does not pass, the harness and the sheet 40 cannot come into contact with each other, so there is no need to apply special processing to the heat dissipation opening 80. By omitting the special processing related to the heat dissipation opening 80, the production efficiency of the part (back panel) can be improved. Also, by not applying special processing to the heat dissipation opening 80, the area of ​​the sheet 40 can be made larger, and the noise resistance performance can be improved.

[0057] In this embodiment, the sheet 40 is provided on the inner side of the back plate 3, and the wiring opening 70 (wiring opening 71 and wiring opening 72) and the heat dissipation opening 80 are provided on the back plate 3 (see FIG. 4). The housing 1 includes a top plate 2, a back plate 3, a bottom plate 4, a left plate 5, and a right plate 6. The sheet 40 may be provided on the inner side of a plate other than the back plate 3, and the wiring opening 70 (wiring opening 71, wiring opening 72) and / or the heat dissipation opening 80 may be provided on the plate. In other words, the sheet 40 may be provided on the inner side of at least one plate, and the wiring opening 70 (wiring opening 71, wiring opening 72) and / or the heat dissipation opening 80 may be provided on the plate. The wiring opening 70 (with specific processing) and the heat dissipation opening 80 (without specific processing) may be provided on different plates. The wiring opening 71 for the power harness and the wiring opening 72 for the outer end plate harness may be provided on different plates.

[0058] In this embodiment, noise resistance can be further improved by providing sheet 40 on the inner surfaces of the side panels (left panel 5 and / or right panel 6) in addition to the inner surface of the back panel 3. Furthermore, noise resistance can be further improved by providing sheet 40 on the inner surfaces of the top panel 2 and / or bottom panel 4.

[0059] The top plate 2 has an opening (top plate opening 2a: screw hole shown in FIG. 3) through which a fastener (e.g., a screw) for fixing the cabinet 1 to an island facility of an amusement facility is passed (inserted). The fastener is screwed into the top plate opening 2a from the inner side of the top plate 2 and fastened (screwed from bottom to top). Inside the cabinet 1, a board unit (e.g., relay board unit) having a predetermined board (e.g., relay board) is provided. The board unit includes a board and a case for accommodating the board, and components (electronic components, connectors, etc.) are arranged on the board surface of the board. The case also includes a connector opening for exposing the connector. The board is arranged so that the board surface faces the top plate 2.

[0060] When the sheet 40 is attached to the inner surface of the top plate 2, the sheet 40 may be scraped off when the fastener is inserted into the top plate opening 2a, causing metal powder (dust) to fall downward. If the metal powder falls and enters the board unit (through the connector opening), it may cause a short circuit in the board circuit (component failure). Therefore, the sheet 40 may not be provided on the inner surface of the top plate 2 among the inner surfaces of the housing 1. In other words, preventing component failure may be prioritized over noise countermeasures. In this case, component failure caused by metal powder falling due to scraping of the sheet 40 when the housing 1 is fixed to the island equipment can be prevented.

[0061] In this embodiment, the harness (wiring) is passed through the wiring opening 70 (wiring opening 71 and wiring opening 72) that has been subjected to a specific processing, but the member that is passed through the wiring opening 70 is not limited to a wiring, and may be another member (conductive member: game medal, screw, nail, etc.). Also, the wiring opening 70 may be a medal supply hole, a screw hole, or a nail hole. Since the wiring opening 70 has been subjected to a specific processing, it is possible to prevent the other member from coming into contact with the sheet 40.

[0062] The gaming machine of this embodiment is A gaming machine equipped with a cabinet (e.g., cabinet 1), A predetermined plate (e.g., back plate 3, bottom plate 4) constituting the outer shape of the housing has a metal sheet (e.g., sheet 40) on the inner side, The predetermined plate is provided with through holes (e.g., small openings 72a, medal supply holes, screw holes, nail holes) for passing conductive members (e.g., wiring, game medals, screws, nails), The sheet has a sheet opening (e.g., sheet opening 42) for passing the conductive member therethrough; The seat opening is larger than the through hole.

[0063] In addition, the gaming machine of this embodiment has A gaming machine equipped with a cabinet (e.g., cabinet 1), A back plate (e.g., back plate 3) that constitutes the outer shape of the housing is provided with a metal sheet (e.g., sheet 40) on the inner side, the back plate includes a first back plate opening (e.g., a wiring opening 72) for passing wiring (e.g., an outer end plate harness); The sheet has a first sheet opening (e.g., sheet opening 42) for passing the wiring therethrough; The first back panel opening is such that a first back panel inner surface opening (e.g., first back panel inner surface opening G) on the inner surface side of the back panel is larger than a first back panel outer surface opening (e.g., first back panel outer surface opening F) on the outer surface side of the back panel, The first sheet opening is adapted to mate with the first back panel inner surface opening.

[0064] If the wiring (conductive member) comes into contact with the metal sheet, the sheet may curl or peel off, and the peeling of the sheet may cause failure of components inside the housing. In addition, the wiring (conductive member) may be scratched and damaged (such as broken wires). In the gaming machine of this embodiment, contact between the wiring (conductive member) and the metal sheet can be suppressed, and the occurrence of these problems can be suppressed. Furthermore, by providing a metal sheet on the inner side of a specified plate (back plate), noise resistance can be improved. This makes it possible to provide a gaming machine that combines a noise countermeasure effect with a component damage suppression effect.

[0065] In addition, in the gaming machine of this embodiment, The side plates (e.g., the left side plate 5 and the right side plate 6) that form the outer shape of the housing are provided with the sheet on their inner surfaces, The top plate (e.g., top plate 2) constituting the outer shape of the housing does not have the sheet on the inner side, The top plate has a top plate opening (e.g., top plate opening 2a) for passing a fastener therethrough, A substrate unit (e.g., a relay substrate unit) having a predetermined substrate (e.g., a relay substrate) is provided inside the housing, The predetermined substrate is disposed so that the substrate surface faces the top plate.

[0066] By providing sheets on the side panels as well, noise resistance can be further improved.Also, by not providing a sheet on the top panel, it is possible to prevent metal powder generated when the case is fixed to the island equipment from adhering to the circuit board inside the case and causing component failure.

[0067] In addition, in the gaming machine of this embodiment, The back plate has a second back plate opening (e.g., heat dissipation opening 80) for dissipating heat, the sheet has a second sheet opening (e.g., sheet opening 44) corresponding to the second back panel opening; The second back plate opening is configured such that a second back plate inner surface opening (second back plate inner surface opening P) on the inner surface side of the back plate matches a second back plate outer surface opening (second back plate outer surface opening Q) on the outer surface side of the back plate, The second sheet opening is adapted to mate with the second back panel inner surface opening.

[0068] Regarding the heat dissipation holes, the opening on the inner surface of the back plate is aligned with the opening on the outer surface of the back plate, and the second sheet opening is aligned with the opening on the inner surface of the back plate, thereby making it possible to increase the area of ​​the sheet and improve noise resistance.

[0069] FIG. 10 shows a position at the lower right of the inner surface of the back panel 3, which is the rear side of the cash box 12 (FIG. 3). The back panel 3 is provided with a pair of conductive rods, a first conductive rod 111 (first sensor) and a second conductive rod 112 (second sensor). The first conductive rod 111 and the second conductive rod 112 protrude forward by a predetermined length. The first conductive rod 111 and the second conductive rod 112 are arranged in a vertical line at a predetermined interval. Metal fittings (crimp terminals, connection terminals) are connected to the bases of the first conductive rod 111 and the second conductive rod 112, and the metal fittings are connected to a harness (wiring).

[0070] The first conductive rod 111 and the second conductive rod 112 can be housed (enter) inside the cash box 12. As described above, surplus medals are supplied to the cash box 12 from the hopper unit 11. When game medals are supplied to the cash box 12, the game medals gradually accumulate inside the cash box 12 and come into contact with the second conductive rod 112 below. At this point, the first conductive rod 111 and the second conductive rod 112 are not electrically conductive.

[0071] Furthermore, when game medals are supplied to the cash box 12, the accumulated game medals come into contact with the first conductive rod 111 above. At this time, the first conductive rod 111 and the second conductive rod 112 are electrically connected. When the first conductive rod 111 and the second conductive rod 112 are electrically connected, a signal is input to the main control board, and the main control board detects an error (cash box full error) based on the input of the signal. The main control board transmits a command indicating the detection of the error to the sub-control board, and upon receiving the command, the sub-control board notifies the occurrence of the error via the performance device. This allows a staff member at the game arcade to notice the occurrence of the error and perform work to resolve the error.

[0072] In this embodiment, the periphery of the first conductive rod 111 and the second conductive rod 112 in the back plate 3 is a recess 120. The recess 120 is in a vertically long, substantially rectangular shape, and is recessed toward the rear by a predetermined length (for example, about 5 mm). No special processing (countersinking) is performed on the recess 120. Here, the opening of the recess 120 on the inner surface side of the back plate 3 is referred to as an inner surface opening T.

[0073] The sheet 40 has a sheet opening 45 (fourth sheet opening) corresponding to the recess 120. The sheet opening 45 is formed so as to align with the inner surface opening T. As a result, the sheet 40 is not provided on the inside (bottom and side surfaces) of the recess 120, and the material (e.g., wood) constituting the back panel 3 is exposed inside the recess 120.

[0074] (Modification) In this embodiment, a metal sheet 40 is attached to the inner side of a wooden plate (for example, the back plate 3), and the wiring opening 70 (the wiring opening 71 and the wiring opening 72) is specially processed. In this modified example, at least one plate (assumed to be the back plate 3) constituting the housing 1 is made of metal, and the sheet 40 is not attached to the inner side of the plate. By making at least one plate (the back plate 3) of the housing 1 out of metal, it is possible to improve the noise resistance performance (even without providing the sheet 40). The metal back plate 3 is provided with a wiring opening for the power harness (or for the outer end plate harness). Since the wiring opening is an opening (hole) provided in the metal plate, if the harness comes into contact with the opening, there is a high possibility that the harness will be damaged. No special processing is applied to the wiring opening in this modified example. In this modified example, instead of special processing, a rubber (non-conductive material) ring is attached to the wiring opening. The annular rubber ring is fitted so as to cover the entire circumference of the opening of the wiring opening, and the harness passes through the inside of the ring. Therefore, the harness may come into contact with the rubber ring, but does not come into contact with (the opening in) the metallic back plate 3. This makes it possible to prevent the harness from being damaged (broken). In this modified example, a heat dissipation opening is provided in a metal plate (for example, back plate 3), but no rubber ring is attached to the heat dissipation opening through which no wiring passes.

[0075] (Second embodiment) Next, a second embodiment of the present invention will be described. The gaming machine according to this embodiment basically has the same configuration as the gaming machine according to the first embodiment, so the description of the same configuration as the gaming machine according to the first embodiment will be omitted or simplified.

[0076] The gaming machine of this embodiment is a gaming machine 101 in which a game is played by using a gaming value as electronic information without using gaming medals as a gaming medium, and the gaming value is consumed or awarded. The gaming machine 101 (FIG. 11) is a so-called Smart Pachi Slot (registered trademark). Unlike conventional slot machines in which physical medals are inserted when playing a game and physical medals are paid out when a winning combination is achieved, the gaming machine 101 is a gaming machine (medalless gaming machine) in which a gaming value as electronic information is used without using physical medals, and the gaming value is consumed or awarded by playing a game. In addition, the gaming value in a medal-less gaming machine corresponds to medals, which are the gaming value in a conventional slot machine, and since the gaming value in a medal-less gaming machine can be understood as a virtual medal (electronic medal), the gaming value in this embodiment may be referred to as a medal (gaming medal). In addition, hereinafter, the number of gaming values ​​may be regarded as the number of virtual medals, and the number of gaming values ​​may be indicated as "~ pieces" or "~ pieces".

[0077] FIG. 11 is a perspective view of a gaming machine 101 as viewed from the front side. As shown in FIG. 11, the gaming machine 101 of this embodiment includes a box-shaped cabinet 1 with an opening on the front side, which faces the player, and a front door (front door) 12 for opening and closing the front opening of the cabinet 1. The front door 12 is divided into an upper door 12a and a lower door 12b, and the upper door 12a and the lower door 12b can be opened and closed freely relative to the cabinet 11. The front door 12 may be an integrated structure that is not divided into the upper door 12a and the lower door 12b. The housing 1 is formed in a box shape with an open front side (having a front opening). The housing 1 includes a top plate 2, a back plate 3, a bottom plate 4, and left and right side plates 5, 6. The left side plate 5 is referred to as the left side plate 5, and the right side plate 6 is referred to as the right side plate 6. In this embodiment, the top plate 2, back plate 3, bottom plate 4, left side plate 5, and right side plate 6 are made of wood. Note that some of the plates may be made of resin.

[0078] In this embodiment, the plate surfaces of the top plate 2, back plate 3, bottom plate 4, left plate 5, and right plate 6 facing the inside of the housing 1 are called "inner surfaces." The lower surface of the top plate 2, the front surface of the back plate 3, the upper surface of the bottom plate 4, the right surface of the left plate 5, and the left surface of the right plate 6 are "inner surfaces."

[0079] In this embodiment, the surfaces of the top plate 2, back plate 3, bottom plate 4, left plate 5, and right plate 6 that face the outside of the housing 1 are called "outer surfaces." The top surface of the top plate 2, the back surface of the back plate 3, the bottom surface of the bottom plate 4, the left surface of the left plate 5, and the right surface of the right plate 6 are "outer surfaces."

[0080] The cabinet 11 contains a reel unit in which a rotatable first reel 15a, a second reel 15b, and a third reel 15c are unitized, a main control means, a sub-control board, a game value number control board, and the like.

[0081] A liquid crystal display 13 (display means) is provided at approximately the center of the upper door 12a as a presentation device. Various images (presentation images) for assisting or livening up the game are displayed on the liquid crystal display 13. A speaker 14 (sound output means) is provided at the lower door 12b as a presentation device. Various presentation sounds (music, sound effects, voice, etc.) for assisting or livening up the game are output from the speaker 14. A lamp 38 (illumination device, illumination means, peripheral lamp) for providing notifications, presentations, etc. may be provided at the front door 12. Note that a movable accessory that can be operated by an actuator, etc. may be provided as a presentation device.

[0082] In addition, a display window 16 is provided on the upper door 12a. A reel unit is arranged behind the display window 16 (first display area 13a described later) so that a part of the reel unit can be seen through the display window 16. The outer circumferential surface of each of the reels 15a to 15c is divided into 20 frames (20 areas) at regular intervals, and one of a plurality of types of symbols is arranged in each frame. In other words, a plurality of types of symbols are arranged in a line on the outer circumferential surface of each of the reels 15a to 15c. When each of the reels 15a to 15c stops, three symbols (upper row symbols, middle row symbols, lower row symbols) are displayed per reel through the display window 16. In addition, the display window 16 is provided with an upper row, a middle row, and a lower row as display positions for viewing the symbols of each of the reels 15a to 15c, and a winning line is set by a combination of the display positions of each of the reels 15a to 15c. In this embodiment, an active line is formed by the top row of the first reel 15a, the middle row of the second reel 15b, and the bottom row of the third reel 15c.

[0083] In this embodiment, the number of game values ​​(prescribed number, prescribed number of coins) required for one game is set to three, and when the prescribed number of game values ​​is inserted, the active line is activated. When the game starts, the reels 15a to 15c start to rotate, and an internal lottery is executed to determine whether any of the winning roles will be won or not (not won). Next, when the reels 15a to 15c stop, if a symbol combination corresponding to the winning role won in the internal lottery is displayed on the active line, this winning role will be a prize, and a process (award winning process) corresponding to the winning role that has been won is executed. That is, whether or not the winning role has been won is displayed according to the symbol combination displayed through the display window 16 when the reels 15a to 15c stop. The active line can be said to be a line for determining whether or not the winning role has been won.

[0084] The lower door 12b (the operation unit installation stand) is provided with a bet button 35 which is operated when betting (depositing) game value, a start lever 32 (game start operation means) which is operated when starting a game, a stop button 33 (stop operation means) (stop buttons 33a, 33b, 33c) which is operated when stopping the spinning reels, and a performance button 36 (performance operation means) which is operated when progressing a performance, etc. In addition, the bet buttons 35 may be provided as a MAX bet button (first bet button) that is operated when betting three game values ​​(prescribed number), and a 1 bet button (second bet button) that is operated when betting one game value.

[0085] The effect button 36 is operated when progressing the effect (changing the aspect of the effect), etc. The effect button 36 is formed to be operable by pressing, and when pressed, for example, the aspect of the effect image displayed on the liquid crystal display 13 changes. By providing the effect button 36 and enabling its operation at a predetermined opportunity, it is possible to increase the player's awareness of participating in the game and improve the interest of the game. For example, the effect button 36 becomes operable during the execution of an effect that makes the player expect a transition to an advantageous state, and an image instructing the operation is displayed on the liquid crystal display 13 (PUSH effect). Then, when the effect button 36 is operated, the result of the game (for example, whether or not a transition to an advantageous state occurs) is notified. Note that the effect button 36 is not limited to a button-shaped button, but may be a lever-shaped button, etc., as long as it is configured to be capable of detecting the operation of the player.

[0086] Further, the lower door 12b is provided with a door key cylinder 66. The lower door 12b (front door 12) can be unlocked by inserting a door key into the door key cylinder 66. Specifically, the lower door 12b can be unlocked by rotating (twisting) the door key inserted into the door key cylinder 66 clockwise from its initial position. Note that an error may be released by rotating (twisting) the door key inserted into the door key cylinder 66 counterclockwise from its initial position.

[0087] Further, the lower door 12b is provided with a lower panel 39. A light source (LED) for illumination is provided on the rear side of the lower panel 39, and the lower panel 39 is illuminated from behind by light emitted from this light source.

[0088] Although not shown in the figure, a dedicated unit (game value lending device, game medal lending device) as a device for lending game value is provided on the side (right side) of the gaming machine 101. In addition, on the front side of the dedicated unit, there are provided a bill insertion port into which bills can be inserted, a card insertion / ejection port into which a card (game value management medium) can be inserted / ejected, a lending button (lending operation means), a replay button (lending operation means), a card return button, and the like.

[0089] In the dedicated unit, an operation (pressing operation) on the loan button is accepted as a loan operation (game value transfer operation) for transferring game value to the gaming machine 101. When the loan button is pressed, a predetermined number (e.g., 50 coins) of game value is credited to the gaming machine 101 by consuming a stored value stored as a prepaid balance on a bill inserted in a bill insertion slot or a card. Also, in the dedicated unit, an operation (pressing operation) on the replay button is accepted as a loan operation (game value transfer operation) for transferring game value to the gaming machine 101. When the replay button is pressed, a predetermined number (e.g., 50 coins) of game value is credited to the gaming machine 101 by consuming a game value owned by the player and managed by a card (game value linked to the card). In this embodiment, an operation on the loan button or replay button as a loan operation means is accepted as a loan operation (game value transfer operation), and based on the loan operation, a predetermined amount of game value is transferred (loaned) from the dedicated unit to the gaming machine 101.

[0090] The lower door 12b is provided with a game medal number display device 211 (game value number display device, game value number display), a count button 212, and a settlement button 218. The game medal number display device 211 and the count button 212 are provided on the side (right side) of the lower door 12b. Based on the lending operation in the dedicated unit 200, in the game machine 101, a value equivalent to a predetermined number of game values ​​is set in credits (game value number storage area). The stored value in the game value number storage area can also be called the number of credits (reserved number, possessed number). The number of credits (number of game medals available for play) is displayed on the game medal number display device 211. The game medal number display device 211 has a 5-digit (or 6-digit) 7-segment display device, and the 7-segment display device is configured to display the number of credits. In the game machine 101, the upper limit of the number of credits may be set within the range of values ​​that can be displayed on the game medal number display device 211, for example. In the gaming machine 101, when the bet button 35 is operated in a state where the gaming value is stored as credit, the gaming value stored as credit is set to a deposited state up to a prescribed number.

[0091] The game value number control board (game value number control means) controls the number of game values ​​stored in the game value number storage area. The game value number control board increases the number of credits by a predetermined number when a predetermined role (minor role) is won and a predetermined number of game values ​​is awarded. In addition, when an operation to insert game values ​​(operation of the bet button 35) is performed at the start of a game, the game value number control board decreases the number of credits by the number of game values ​​inserted. The game medal number display device 211 displays a value obtained by subtracting the number of bets from the number of owned medals (number of credits).

[0092] The game value number control board also controls the reception of game value transferred from the dedicated unit to the game machine 101. When game value is transferred from the dedicated unit to the game machine 101, the game value number control board increases the number of credits by the amount of game value transferred. The game value number control board also controls the transfer of game value from the game machine 101 to the dedicated unit. When game value is transferred from the game machine 101 to the dedicated unit, the game value number control board decreases the number of credits by the amount of game value transferred. The game value number control board also causes the number of game values ​​(number of credits) stored in credits to be displayed on the game medal number display device 211, and changes the display content of the game medal number display device 211 according to the increase or decrease in the number of credits.

[0093] The counting button 212 is a button that is operated when transmitting (returning, transferring) information (credits) indicating a value equivalent to a predetermined number of credits (all or part of the number of credits) to the dedicated unit. The counting button 212 has a pressing portion (operation portion), which is formed so as to be capable of being pressed. When the player ends a game, for example, the credited game value can be transferred from the gaming machine 101 to the dedicated unit based on an operation (pressing operation) on the counting button 212 as a counting operation (return operation). Then, when an operation (pressing operation) is performed on the card return button after the game value has been transferred to the dedicated unit, a card that allows the number of game values ​​owned by the player to be known is discharged from the dedicated unit (card insertion / ejection port).

[0094] Based on the lending operation in the dedicated unit, a predetermined number of game values ​​(game medals) are provided to the gaming machine 101 (the number of credits is added). Next, when the bet button 35 is operated, the game values ​​are set to an inserted state up to a predetermined number, and a value corresponding to the number of game values ​​(number of game medals) set to the inserted state is subtracted from the number of credits. That is, the number of game values ​​displayed on the game medal number display device 211 decreases. When the predetermined number of game values ​​is set to the inserted state, the operation of the start lever 32 becomes valid, that is, the game can be started. Next, when a game start operation is performed on the activated start lever 32, the rotation of each of the reels 15a to 15c begins. Next, when the rotation speed of the reels increases to a predetermined speed and reaches a steady rotation state, the operation of the stop buttons 33a to 33c becomes valid. Next, when the activated stop buttons 33a to 33c are operated, the rotation of the corresponding reel stops. Next, when all the reels 33a to 33c have stopped spinning, a process of granting a predetermined amount of game value (adding it to the credits) according to the result of the game, a process of making it possible to start the game again without consuming new game value (replay process), etc. are performed, and one game (one game) ends. When the counting button 212 is operated, a predetermined amount of credits (game medals) are sent (returned) to the dedicated unit. When a card return operation is performed in the dedicated unit, a card on which predetermined information is stored is discharged from the dedicated unit 200.

[0095] In addition, when the settlement button 218 is operated (pressed) in a state in which the game value is set to an inserted state (bet) in the gaming machine 101, the inserted game value is returned to credits. The settlement button 218 is a button that is operated when returning the game value inserted (set to an inserted state) by operating the bet button 35 to credits (game value number storage area). In other words, a process (introduction return process) is executed to return the game value set to the inserted state to credits based on the operation of the settlement button 218. The insertion return process is a process in which the setting of the inserted state of the game value is canceled, and a value equivalent to the number of game values ​​set to the inserted state is added to the number of credits (the stored value in the game value number storage area). When the settlement button 218 is operated in a state in which the game value set to the inserted state exists, the game value is returned (returned) to credits based on that, and the number of game medals displayed on the game medal number display device 211 increases.

[0096] The main control board is provided with a setting change key cylinder, a setting change button, and the like. The setting change key cylinder and the setting change button may be provided in other parts, such as a power supply unit. The setting change key cylinder (setting key switch) has two states, an OFF state and an ON state. In other words, it is switchable between an OFF state and an ON state. The setting change key cylinder is formed so that a setting key can be inserted. The setting change key cylinder is in an OFF state in an initial state. When the inserted setting key is rotated 90 degrees clockwise from the initial position, the state of the setting change key cylinder is switched from an OFF state to an ON state. When the setting key is rotated 90 degrees counterclockwise so that the state of the setting change key cylinder is switched from an ON state to the initial position, the state is switched from an ON state to an OFF state. The setting change button can be pressed.

[0097] The main control board receives input signals from input means such as the bet button 35, the start lever 32, and the stop buttons 33a to 33c, performs various calculations for executing the game, and controls output means such as the reel unit based on the calculation results.

[0098] The sub-control board receives signals sent from the main control board and input signals from input means such as the performance button 36, performs various calculations to execute the performance, and controls the performance devices such as the LCD display 13 and speaker 14 based on the results of the calculations.

[0099] The main control board and the sub-control board are electrically connected, and various information (signals) such as information indicating the game status can be transmitted from the main control board to the sub-control board, but information cannot be transmitted from the sub-control board to the main control board. The functions of each board, such as the main control board and the sub-control board, are realized by hardware such as various processors (CPU, DSP, etc.), ICs, or information storage media such as ROM and RAM, or software consisting of a predetermined program pre-stored in ROM, etc.

[0100] Conventional slot machines are equipped with a medal slot, a receiving tray, a hopper unit, a cash box, etc., but the gaming machine 101 does not have these components.

[0101] FIG. 12 is a perspective view showing the inside of the housing 1. Inside the housing 1, a power supply unit 210 is arranged, which includes a power supply board (power supply means) for supplying power to each component. The power supply unit 210 is in the shape of a substantially rectangular parallelepiped box, and is arranged at the lower left inside the housing 1 (placed on the bottom plate 4). The power supply unit 210 includes a power switch (not shown), and when the power switch is turned on, power is supplied from the power supply unit 210 to each component. Note that some components may be configured to receive power even when the power supply unit 210 is in an OFF state. Although not shown, a power cable (power supply harness) connected to a receptacle that supplies commercial power (AC 100V) is connected to a power connector provided on the power supply unit 210. Specifically, a connector provided on one end of the power supply harness is connected to the power connector, and a plug provided on the other end of the power supply harness is connected to the receptacle. The power supply board of the power supply unit 210 creates a DC power supply (for example, 5V, 12V, 24V, etc.) from power sent from outside the gaming machine via a power harness, and supplies power to each component of the gaming machine.

[0102] Inside the cabinet 1, a game ball etc. lending device connection terminal board 220 is attached to the inner side of the left side plate 5. The game ball etc. lending device connection terminal board 220 is a connection terminal board for connecting the game machine 101 and the dedicated unit. In other words, the game machine 101 and the dedicated unit are connected via the game ball etc. lending device connection terminal board 220. One end of a terminal board harness 221 is connected to the connector of the game ball etc. lending device connection terminal board 220, and the other end of the terminal board harness 221 is connected to the dedicated unit. The dedicated unit is connected to an external electronic device (such as a hall computer).

[0103] In the gaming machine of this embodiment, as in the gaming machine of the first embodiment, a metal sheet 40 is attached to the inner side of the cabinet 1 (for example, the back panel 3). In addition, a wiring opening 70 (first back panel opening) and a heat dissipation opening 80 (second back panel opening) are provided in the board (hereinafter referred to as the back panel 3) on which the sheet 40 is provided. The wiring opening 70 includes at least a wiring opening 71 for passing a power harness connected to the power supply unit 210, and a wiring opening 72 for passing a terminal board harness 221 connected to the gaming ball etc. dispensing device connection terminal board 220.

[0104] The wiring opening 70 through which the harness passes is specially processed (for example, countersinking), but the heat dissipation opening 80 through which the harness does not pass is not specially processed (for example, countersinking). The wiring opening 70 has a larger diameter on the first back plate inner side opening than on the first back plate outer side opening. The wiring opening 70 has a larger opening on the inner side of the back plate 3 (housing 1) than on the outer side of the back plate 3.

[0105] The sheet 40 has a sheet opening (for example, the sheet opening 42 in FIG. 6) corresponding to the wiring opening 70. The sheet 40 also has a sheet opening (for example, the sheet opening 44 in FIG. 9) corresponding to the heat dissipation opening 80.

[0106] By aligning the sheet opening (first sheet opening) corresponding to the wiring opening 70 (wiring opening 72 in FIG. 6) with the first back panel inner side opening (first back panel inner side opening G in FIG. 6) (by shifting the position of the end of the sheet 40 outward), the harness can be prevented from coming into contact with the sheet 40. By preventing the harness from coming into contact with the sheet 40, the following effects are achieved. (1) If the harness comes into contact with the sheet 40, problems such as the end of the sheet 40 turning over, a part of the sheet 40 peeling off (partially tearing), and the peeled-off sheet 40 coming into contact with a board in the housing 1 and causing a short circuit (component failure) can be caused. However, this can prevent such problems from occurring. (2) If the harness comes into contact (rubs) with the end (edge) of the sheet 40, the harness can be damaged (the harness coating can be torn), and there can be a risk of a disconnection or the like. However, this can prevent such problems from occurring. In addition, even if the covering of the harness is peeled off and the conductor is exposed, it is possible to reduce the possibility that the conductor will come into contact (become electrically conductive) with the sheet 40. According to this embodiment, it is possible to provide a gaming machine that combines a noise suppression effect by the sheet 40 and an effect of suppressing damage (failure) of parts by the specific processing.

[0107] The present invention is not limited to the above-described embodiment, and can be modified in various ways without departing from the gist of the present invention. Furthermore, the present invention allows free combination of the embodiments, modification of any of the components of the embodiments, or omission of any of the components of the embodiments, within the scope of the invention. For example, the configuration of the slot machine is not limited to that of the above-described embodiment. Furthermore, the above-described configuration can be applied not only to slot machines, but also to other gaming machines. [Explanation of symbols]
